Technical Highlights

	Supply forms: Round, square, flat, ring, hollow, and custom profiles are produced from austenitic, ferritic, duplex, and selected nickel alloys - matched to ASTM / JIS / GB listings and your machining or fabrication route.
	Processing & finish: Hot-rolled and cold-drawn stock, centerless grinding for tight OD, and finishes from No.1 through BA / No.4 / decorative polish - selected to suit corrosion resistance, appearance, or downstream turning requirements.
	Quality & documentation: Chemical and mechanical properties follow standard mill sheets; MTC (e.g. EN 10204 3.1) and PMI or retest can be aligned with your purchase order and project ITP.
	What to send for a quote: Grade, shape, diameter or section size, length, quantity, standard reference, and finish - we confirm availability, tolerance class, and delivery.
